Solve for J
J=\frac{1}{2}-\frac{1}{2}i+\frac{1+2i}{x}
x\neq 0
Solve for x
x=\frac{2+4i}{2J+\left(-1+i\right)}
J\neq \frac{1}{2}-\frac{1}{2}i

-1-2i+Jx=\frac{x}{1+i}
Use the distributive property to multiply i-2 by i.
Jx=\frac{x}{1+i}+\left(1+2i\right)
Add 1+2i to both sides.
xJ=\left(\frac{1}{2}-\frac{1}{2}i\right)x+\left(1+2i\right)
The equation is in standard form.
\frac{xJ}{x}=\frac{\left(\frac{1}{2}-\frac{1}{2}i\right)x+\left(1+2i\right)}{x}
Divide both sides by x.
J=\frac{\left(\frac{1}{2}-\frac{1}{2}i\right)x+\left(1+2i\right)}{x}
Dividing by x undoes the multiplication by x.
J=\frac{1}{2}-\frac{1}{2}i+\frac{1+2i}{x}
Divide \left(\frac{1}{2}-\frac{1}{2}i\right)x+\left(1+2i\right) by x.
